Subject [jira] [Updated] (MAPREDUCE-3428) MR AppMaster CLASSPATH is dependent on the compile-time environment
Date Fri, 18 Nov 2011 10:06:51 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3428?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ahmed Radwan updated MAPREDUCE-3428:
------------------------------------

    Description: 
The CLASSPATH for the MapReduce Application master is set using compile time path information,
which is typically different from run-time. This will cause failure when running on different
environments.

Specifically, the YarnRunner, and as part ApplicationSubmissionContext creation, sets the
classpath for the application master using MRApps.setClasspath(environment), and then the
setMRFrameworkClasspath(..) method uses compile time path information present in the "mrapp-generated-classpath"
file (created at compile-time).
